FIELD OF THE DISCLOSURE

The present disclosure relates generally to a method and system for use in connection with a network-based messaging system and a remote subscriber terminal.

BACKGROUND

Network-based messaging systems, such as voice-mail systems have been replacing stand-alone answering machines that connect to an individual subscriber telephone. Such network-based messaging systems offer many advantages over stand-alone answering machines, including advanced voice-mail features such as remote message retrieval and user convenience. However, one advantage of the stand-alone answering machines over network-based messaging is that the user can monitor an incoming message in real-time and determine if they want to intercept the message and engage in a conversation with the caller (i.e., call screening). Conventional network-based messaging systems have not offered a call screening feature.

DETAILED DESCRIPTION

The present disclosure is generally related to methods for use in connection with network-based messaging systems and related systems.

In accordance with a particular embodiment, the method includes receiving a call at the network-based messaging system and providing a notification to a subscriber of the network-based messaging system that the call has been received and that a message for the subscriber is to be recorded. The subscriber is located remotely from the network-based messaging system.

In accordance with another particular embodiment, the method includes receiving a notification that the call has been received at the remote network-based messaging system and screening the call by monitoring a voice message played at a subscriber terminal while the voice message is being recorded at the remote network-based messaging system.

In accordance with another particular embodiment, the system includes a computer server and a notification module. The computer server is associated with the remote subscriber terminal and includes a voice message storage unit to store voice messages. The notification module is to notify the remote subscriber terminal when a call is received at the computer server and when a voice message is to be recorded.

In accordance with another embodiment, the system includes a gateway responsive to a call destined for a telephone subscriber, a media server responsive to the gateway, an application server associated with a remote subscriber computing device, and a directory server responsive to the media server. The media server includes a voice-mail greeting and voice-mail prompt generator. The application server provides a notification to the remote subscriber computing device in response to a call being received at the media server. The directory server is to identify the application server registered for use by the subscriber.

Referring to FIG. 1, a system 100, including a network-based messaging system, is disclosed. The system 100 includes the public switched telephone network (PSTN) 102, the public internet 104, a voice gateway 106, a media server 108, and an application server 110. The system 100 further includes a directory server 112 accessible by the media server 108, a representative call originator 114, a personal computer used as a subscriber data terminal 120, a telephone subscriber 116, and an alternate phone number for the subscriber 118.

In this particular embodiment, the telephone service subscriber 116 and the alternate phone number 118 are coupled to the PSTN 102. Likewise, the call originator 114 is also coupled to the PSTN 102. The media server 108 is coupled to the voice gateway 106 via a Voice over Internet Protocol connection 122 (VoIP). The media server 108 includes an audio greeting generator and voice message prompt unit 128 and voice message storage 130. The personal computer subscriber terminal 120 includes client service software 216. A subscriber terminal 120 is coupled to the public internet 104 via a conventional connection 132, such as a modem or a high speed data connection.

During operation, a telephone call originated by caller 114 is originally directed towards a telephone destination for the subscriber, such as telephone service subscriber 116. In the event that the telephone subscriber 116 has a busy line, or is otherwise engaged, the call from originator 114 may be directed to the voice gateway 106. In this scenario, the voice gateway 106 converts the phone call from the originating caller 114 to a voice over internet protocol (VoIP) data packet call 122 and directs the call to the media server 108. The media server 108 requests, via the directory server 112, an appropriate application server associated with the destination subscriber 116. Using a look-up function with the directory server 112, the media server 108 determines that the destination subscriber 116 is connected online via subscriber terminal 120 and determines the associated application server 110 to support such subscriber. In this illustrated case, the associated application server to support the subscriber 116 is the application server 110. Although only a single application server is shown, it should be understood that the media server 108 may be coupled to many different application servers that support different subscribers.

After determining the associated application server 110, and upon receipt of the call at media server 108, an audio greeting is produced by audio greeting generator 128 and a voice message prompt such as a “beep” tone that prompts the caller 114 to leave a message. As the message is to be left by the caller 114 and stored within the voice message storage unit 130, the application server 110 sends a notification message via the internet 104 to the subscriber terminal 120. At this point, a notification may be displayed to the subscriber terminal 120, such as via a pop-up screen that lets the subscriber 120 learn of the message that is to be recorded at the network in the voice message storage unit 130. The subscriber at terminal 120 may elect to ignore the recorded message or may elect to screen the message. In the event the caller decides to screen the incoming message, the voice message being recorded at voice message storage unit 130 is also bridged through the application server 110 to the service subscriber terminal 120. At this point, the subscriber terminal 120 may be used to listen to the message being recorded by caller 114 in real time as the message is being recorded and stored at the voice message storage unit 130 within media server 108. This function is referred to as real-time call screening.

In addition, the subscriber terminal 120 may be used to request an intercept action. In this case, the voice message recording function may be interrupted and the original call may be forwarded to an alternate phone number for the subscriber, such as alternate phone number 118. In this particular example, the media server 108 interrupts the voice message recording and the gateway 106 directs call forwarding through the PSTN 102 such that a phone connection is established between caller 114 and the subscriber using alternate phone 118. Although an alternate PSTN phone number is illustrated, the alternate phone may be another communication device used by the subscriber, such as a cellular phone, the personal computer 120, or any other alternative communication device accessible via either the public switched telephone network (PSTN) 102 or the internet 104.

Referring to FIG. 2, a flow chart is provided that illustrates a method of operation of the system 100. A call is received at a network-based messaging system, at step 202. The subscriber is notified that the call has been received and that a voice message for the subscriber is to be recorded, at step 204. An example display to provide such notification to the subscriber is illustrated in the pop-up screen shot of FIG. 3. Call screening options are provided including a call monitoring option, at 206. An example of a call screening option display is shown in FIG. 4. In addition to the call monitoring option, in the example shown in FIG. 4, other options such as ignoring the message, adding the caller to the address book, canceling the call screening option, and interrupting or accepting the call is shown.

Upon receipt of the subscriber request, such as when the subscriber selects one of the call screening options from the display menu, a call screening action is performed as selected by the subscriber. Examples of call selection actions are accepting the call, ignoring the call, or performing a call intercept operation, at step 208. The subscriber may then be provided with a call interception option menu, such as the display selection shown in FIG. 5, at step 210. Upon subscriber request, such as receiving a subscriber request in response to the display menu shown in FIG. 5, a call interception action is performed. As an example, based on the subscriber request from the display menu of FIG. 5, the system may intercept the call during voice message recording and then route the call to an alternate subscriber terminal. An example of a suitable alternate subscriber terminal is a wireless phone, an alternate telephone, or a soft phone telephone interface at the subscriber computer, such as the interface illustrated in FIG. 6. The soft phone telephone interface and the pop-up displays of FIG. 3-5 may be provided by client software loaded at the subscriber computer, such as the client software 216. The call interception action is illustrated, at step 212.

After completion of the call, such as completion of the call screening operation, or completion of a live call connection to the alternate phone number, the call may be disconnected, at step 214.

Referring to FIG. 7, a more detailed description of the method of operation of the system 100 is illustrated. With this method, the PC client, such as software 216 located within the subscriber computer terminal 120 at the subscriber's location, connects to a remote application server and provides authorization and authentication information, at 702. The application server registers the subscriber client location with the directory server. The subscriber is now set up for call screening operation, at step 704.

A call originator places a call to the subscriber's phone number and there is either no answer or the line is busy. The call is then forwarded to a service access number that terminates on a voice gateway connected to the network-based messaging system, at 706. The gateway converts the call to a voice over internet protocol (VoIP) and connects the call to a media server.

The media server uses the inbound call information provided by PSTN to the gateway connection and determines how to handle the call, at step 708. The media server access the directory server to find subscriber information, including whether the subscriber is online and to which particular application server the subscriber client is currently connected, at 710. The media server sends the application server a message telling it to notify the subscriber of an inbound call. The media server plays the subscriber's greeting to the caller, at 712. The application server sends an inbound call message to the client running on the subscriber's PC, at step 714. A particular example of a pop-up display that notifies the PC client user of the inbound call is illustrated at FIG. 3. At the end of the recorded greeting; the caller is prompted to leave their message, at step 716 and processing continues, at 720.

Referring to FIG. 8, the method is continued from step 720 to method step 802 where the subscriber activates the PC client interface indicating a desire to screen the inbound call. The PC client then notifies the application server of the subscriber selection, at step 802 and as illustrated by the second pop-up display at FIG. 4. The application server informs the media server that it needs to bridge the call with a listen only mode to the PC client, at 804. While the media server stores the message, the subscriber hears the message as it is being left and recorded, at 806. The subscriber clicks on the connect call button at the PC client and the PC client signals the application sever of the subscriber selection as illustrated by the third pop-up display shown in FIG. 5, at step 808. The application server notifies the media server and the media server instructs the caller to wait for a direct connection to the subscriber, at step 810. The media server informs the gateway how to connect the caller to the subscriber, at 812 and the process continues at 820.

Referring to FIG. 9, processing continues from 820 to step 902 where the subscriber has selected a call intercept action from the display menu such as from the display shown in FIG. 5. Based on the subscriber selection, at decision block 904, processing continues either using a VoIP/PC interface, at 906, routing to an alternative subscriber device, at 908, or to an alternate telephone at 910. Where a VoIP connection is selected, the gateway connects the caller to the subscriber to the PC client, for example using the VoIP channel, at 906. Where an alternative subscriber device is selected, the gateway connects the caller to the subscriber using the telephone network. The alternative subscriber device may be accessed through another network, such as a cellular network coupled to the PSTN, in the case where the selected subscriber device is a wireless phone, at 908. Where the alternative telephone is selected, the gateway call transfers the call to the subscriber on the alternate phone using the telephone network, at 910.

The disclosed real-time call screening capability is provided by a multi tiered service that offers the following advantages to the conventional network-based offering: (1) a pop-up alert message that notifies the on-line user that they are receiving a message to their network based mail box; (2) a pop up alert to provide the user the options of a) ignoring the alert and allowing the recording of the message to continue, and b) monitoring the message as it is being recorded; and (3) electing to intercept the message and, and in essence, pick up the call utilizing either an assigned phone (PSTN, wireless, IF, etc) or a derived voice soft phone via the computer. Thus, the disclosed system and method provide enhanced functionality to network-based voice mail.
